“Regrettably, less than 24 hours after receiving this order, a tragic series of events occurred in Traverse City. Our thoughts and prayers are with everyone involved in this devastating situation.”

Chaos unfolded at a Walmart in Michigan after a man burst into the store during a calm shopping afternoon and stabbed 11 people at random, authorities say.

Emergency vehicles and uniformed first responders gathered in the parking lot of the shopping center that houses several other retail stores.
